Sorry, I forgot to include in the last email:
access-list 50 permit any
And I did a "clear ip bgp 144.228.120.130" without the "soft out". Thanks. Ray, Sprintlink On Mon, 10 Feb 1997 bgp4-adm@sprint.net wrote:
Hi, Pierre.
These are the changes I have made in our sl-dc-10 router:
router bgp 1790 neighbor 144.228.120.130 remote-as 6846 neighbor 144.228.120.130 version 4 neighbor 144.228.120.130 distribute-list 50 in neighbor 144.228.120.130 distribute-list 111 out neighbor 144.228.120.130 route-map transit-in in neighbor 144.228.120.130 route-map transit-out out neighbor 144.228.120.130 filter-list 53 in
access-list 50 deny 10.0.0.0 0.255.255.255 access-list 50 deny 172.16.0.0 0.15.255.255 access-list 50 deny 192.168.0.0 0.0.255.255
clear ip bgp 144.228.120.130 soft out
Please let us know if there are any problems with this new configuration. Thank you.

As specified in RFC1918 (ftp://ds.internic.net/rfc/rfc1918.txt) the netblocks 10.0.0.0/16, 172.16.0.0/12 and 192.168.0.0/16 have been allocated for "Private Internets". Consequently, these netblocks should not be routed over the Internet.
As shown below, they are currently advertised from AS6848 and these advertisements are carried to us (AS6453) through various AS's of the SprintLink system.

AS6846 responsibles should take immediate action to remove these announcements. SprintLink, as any conscientious operator, should take action to filter out these announcements from any of its peers.
